All proteins are made of basic secondary structure units, either α-helix or β-sheets, determined by hydrogen bonding between the amino acids within a peptide chain. On a larger scale, structures are ...

The structure of protein sets the foundation for its interaction with other molecules in the body and, therefore, determines its function. This article will cover the structural principles of proteins ...

The protein backbone plays a big role in protein stability. For example, hydrogen bonds between the NH of one amide and the carbonyl oxygen of another are involved in helices, sheets, and every other ...
